As part of the legendary Hooligan DSPL series, this model delivers enormous bass output, precision handling, and competition-ready reliability.

With 4000W RMS and 6000W Max power handling, the HOOL-X15.4DSPL is powered by a 4" black aluminum dual 4-ohm voice coil and a massive 500 oz ferrite motor. Its non-pressed paper cone with a carbon fiber dust cap, reinforced SPL-tuned surround, and heavy-duty spider allow for extreme excursion while maintaining clean, controlled bass at high volumes.
